We'll proceed our systematic method to diagnosing a pool heater by wanting at how to proceed this site in the event the light while in the handle pad around the leading of the Sta-Rite pool and spa heater that is labeled “service heater” is lit. (We are going to continue while using the assumption that you choose to know almost everything from phase one particular.) This time you must get rid of the edges through the heater ahead of disconnecting electricity on the heater to be able to examine the codes within the board hooked up towards the topside. Just after taking away the perimeters, you will see the big topside that's continue to connected to the heater. Beneath the topside is usually a metallic panel that keeps the topside in position. Underneath this panel you will find two locking pins (cotter pins). Very carefully take away the 2 pins and retail outlet them someplace safe right until reassembly. Gently take out the very best and turn it the wrong way up. You will note a lightweight lit about the board you are seeking at whenever you transform the topside about. The sunshine will likely be beside a code which is written around the board.

The first code that you're going to see to the remaining side of the board is going to be PS. This is actually the code for the force change. We covered the force change in segment a person. If this gentle is lit return to phase a single and overview that segment. If essential adhere to the directions to exchange the force switch.

The next code you can see within the board is HLS. If you use a controller over the procedure you must bypass it presently. You have got to meticulously disconnect the ability from your heater. When you are sure the electricity is disconnected, you have got to uncover and open the high-voltage cupboard. This cabinet is really a steel box in the course of the heater. If you are searching on the cupboard, there exists normally a screw within the leading proper side. Loosen the screw along with the doorway will swing down toward you. You need to get incredibly mindful when doing work in this box and only do so if you are sure which the electricity to your heater is OFF.

You will need to bypass the firewall safety interface. To try and do this you'll need a short wire with stab-tab connectors. In case you use a controller and it was adequately installed the wire can have been still left during the box by the tech who set up the controller. If not you have got to make this jumper wire. At this stage search with your owner's manual to identify the 2 good pins to connect to. If you have a very controller or are employing a fireman's swap this is where your manage needs to be linked. If you have a very controller and it is not linked listed here, it may be the source of your respective troubles and either have a very accredited tech proper the trouble or suitable it by yourself.

You must be careful not to set the jumper wire on the energy terminals or you will damage your heater by burning up the electronic process. Make use of your manual to track down the place the fireman's change is supposed to be hooked up and punctiliously attach your jumper in between these terminals. When you now activate the power as well as the heater works with none challenges, your issue lies while in the controller or maybe the wiring going to the controller. You must trouble shoot this technique.

In the event you however hold the exact challenge along with your heater. (“service heater” light arrives on), leave the jumper in place and validate the pump is on and that you've fantastic h2o movement. Make certain once more together with your meter which the strain change is not biking. It should really go through being a dead small. (See segment a person) With excellent water circulation confirmed and the “service heater” gentle on, your difficulty might be one of the thermo-regulators inside the security technique.
